Definitions

  • the present invention relates to an agent for improving lawn grass quality, and more particularly, to an agent for improving lawn grass quality having one or more effects of promotion of dwarfing, by which elongation of lawn grass is suppressed; sturdiness of stem, by which the weight of the stem is increased; increase of leaf count, by which the leaf density is increased; and improvement of greenness, by which the extent of greenness is increased.
  • Lawn grasses are widely used for the purpose of sports, leisure, ornamentation and protection, and they are particularly essential in golf fields.
  • maintaining an appropriate grass height increases the density of stems and leaves, and suppresses germination of weeds. Therefore, it is very important to maintain the grass height by mowing.
  • frequent mowing intended for maintaining the grass height requires efforts, and thus dwarfing agents for lawn grass have been used to reduce such efforts.
  • Known dwarfing agents for lawn grass include various gibberellin biosynthesis inhibitors, and cinnamic acid (Patent Document 1). However, these dwarfing agents for lawn grass do not still give sufficiently satisfactory results.
  • Patent Document 2 discloses 5-aminolevulinic acid used to increase the photosynthetic activity of a plant and the chlorophyl content as well as the green color, the promotion of the organs and the increase of tillers.
  • the inventors of the present invention devotedly conducted an investigation under such circumstances, and they unexpectedly found that when a gibberellin biosynthesis inhibitor, which is a dwarfing agent, is used in combination with 5-aminolevulinic acid, a derivative thereof or a salt of the acid or the derivative, which has a growth promoting effect, not only the dwarfing effect is augmented as compared with the case of using a gibberellin biosynthesis inhibitor alone, but also the effects of making the stems sturdy, increasing the leaf count, and improving greenness can be synergistically increased, while the same effects are manifested weakly or in a reverse manner when the agents are used individually alone. Thus, the inventors completed the present invention.
  • the present invention provides an agent for improving lawn grass quality containing, as active ingredients, 5-aminolevulinic acid or a salt of the acid and a gibberellin biosynthesis inhibitor, wherein the gibberellin biosynthesis inhibitor is at least one selected from trinexapac-ethyl, paclobutrazol, prohexadione calcium salt and flurprimidol.
  • the improvement of lawn grass quality according to the present invention includes at least one of (a) promotion of dwarfing, (b) sturdiness of stems, (c) increase of leaf count, and (d) improvement of greenness.
  • the present invention also provides a method for improving lawn grass quality, including treating lawn grass with 5-aminolevulinic acid or a salt thereof, and a gibberellin biosynthesis inhibitor, selected from trinexapac-ethyl, paclobutrazole, prohexadione calcium salt and flurprimidol.
  • a gibberellin biosynthesis inhibitor selected from trinexapac-ethyl, paclobutrazole, prohexadione calcium salt and flurprimidol.
  • the agent of the present invention can further promote dwarfing of lawn grass as compared with conventional dwarfing agents, and also can make the stems of lawn grass sturdier, further increase the leaf count, and further improve greenness, as compared with the case of using 5-aminolevulinic acid and a gibberellin biosynthesis inhibitor respectively alone.
  • 5-aminolevulinic acid since the compound is known to have a lawn grass growth promoting effect, the compound increases the grass height when used alone. However, when used in combination with a gibberellin biosynthesis inhibitor, 5-aminolevulinic acid gives an unexpected effect of decreasing the grass height, as compared with the case of using a gibberellin biosynthesis inhibitor alone.
  • the agent hardly improves the stem, leaf count and greenness when used alone, since the agent inhibits biosynthesis of gibberellin, which is a plant hormone.
  • the gibberellin biosynthesis inhibitor gives unexpected effects of making the stems sturdy, increasing the leaf count, and improving greenness, as compared with the case of using 5-aminolevulinic acid alone.
  • One of the active ingredients of the quality improving agent of the present invention includes 5-aminolevulinic acid.
  • Examples of the salts of 5-aminolevulinic acid include acid addition salts such as hydrochloride, phosphate, nitrate, sulfate, sulfonate, acetate, propionate, butyrate, valerate, citrate, fumarate, maleate and malate; and metal salts such as sodium salt, potassium salt and calcium salt.
  • acid addition salts such as hydrochloride, phosphate, nitrate, sulfate, sulfonate, acetate, propionate, butyrate, valerate, citrate, fumarate, maleate and malate
  • metal salts such as sodium salt, potassium salt and calcium salt.
  • 5-aminolevulinic acid and salts thereof can be used singly, or as mixtures of two or more of these.
  • 5-aminolevulinic acid, or a salt of the acid can be produced according to any of chemical syntheses, and methods utilizing microorganisms or enzymes.
  • the methods described in JP-A-4-9360 , JP-A-11-501914 , JP-A-2005-314360 , JP-A-2005-314361 and JP-A-2006-182753 may be mentioned.
  • Products thereof can be used directly without going through separation and purification, as long as the products do not contain substances that are harmful to lawn grass. If the products contain any harmful substances, the products can be used after eliminating the harmful substances appropriately to a level that is not regarded as harmful.
  • the plants which are the targets of application of the quality improving agent of the present invention are preferably lawn grasses, more preferably Colonial Bentgrass, Kentucky Bluegrass, Perennial Ryegrass, Zoysia tenuifolia and Zoysia japonica, and even more preferably Zoysia tenuifolia and bentgrass.
  • the agent for improving lawn grass quality of the present invention contains 5-aminolevulinic acid, or a salt of the acid, and a gibberellin biosynthesis inhibitor, but the agent can be further incorporated with, if necessary, plant growth regulators, sugars, amino acids, organic acids, alcohols, vitamins, minerals and the like, in addition to those ingredients.
  • Examples of the plant growth regulators used herein include brassinolides such as epibrassinolides; choline preparations such as choline chloride and choline nitrate; indolebutyric acid, indoleacetic acid, ethychlozate preparations, 1-naphthylacetamide preparations, isoprothiolane preparations, nicotinic acid amide preparations, hydroxyisoxazole preparations, calcium peroxide preparations, benzylaminopurine preparations, methasulfocarb preparations, oxyethylene docosanol preparations, ethephon preparations, cloxyfonac preparations, gibberellins, streptomycin preparations, daminozide preparations, benzylaminopurine preparations, 4-CPA preparations, ancymidol preparations, inabenfide preparations, chlormequat preparations, dikegulac preparations, mefluidide preparations, calcium
